Scale Group Details and Editing

The Scale Group Details tab is the primary view of a scale group's configuration. It shows the plan, name, node counts, and active policies, and — when the group is Running — it is where you edit the node counts and policies inline.

This tab is shown whenever the group is not Stopped, Stopping, or Starting. To resize, stop, start, or delete the group, see Scale Group Actions.

What the Tab Shows

Summary

• Plan Name — the compute plan for group nodes (marked (Private Cloud) for a private cluster).
• Scale Group Name — the group's name.

Scale group parameter

• Minimum nodes — the floor for the pool.
• Maximum nodes — the ceiling for the pool.
• Desired nodes — the current target node count.

Scale group policy

• The policy in effect — Elastic Policy, Scheduled Policy, or Elastic and Scheduled Policy — with the matching detail panel(s) below.

Elastic Policy panel

Field	What it shows
Policy Parameter	The monitored metric (for example, CPU, or your custom attribute name).
Adds a node when …	The scale-up condition — operator (more than / more than equal to) and threshold value.
Removes a node when …	The scale-down condition — operator (less than / less than equal to) and threshold value.
Watch period policy	The number of consecutive periods.
Duration (second)	The length of each period.
Cooldown (second)	The pause after a scaling action.
cURL	For a custom policy, Get cURL reveals the command used to publish the custom metric value to a node. See Custom Scaling Policies.

Scheduled Policy panel

Field	What it shows
Upscale Recurrence	The cron expression for scaling up.
Upscale Desired Nodes	The node count after the upscale cron fires.
Downscale Recurrence	The cron expression for scaling down.
Downscale Desired Nodes	The node count after the downscale cron fires.

Edit Node Counts

Inline editing is available when the group is Running.

To change a node count:

1. On the Scale Group Details tab, select the edit (pencil) icon next to Minimum nodes, Maximum nodes, or Desired nodes.
2. Enter the new value. The portal validates the relationships between the three counts:
   • Minimum nodes must be at least 1, below the desired and downscale counts.
   • Maximum nodes must be above the desired and upscale counts (and at most 50).
   • Desired nodes must be between the minimum and maximum.
3. Confirm the inline edit (the tick icon) or cancel it (the cross icon).
4. Select Update to apply, or Cancel to discard.

Edit the Policy

To change the policy type or its parameters:

1. Select the edit icon next to Scale group policy.
2. Choose the policy from the Select Policy dropdown — Elastic Policy, Scheduled Policy, or Elastic and Scheduled Policy.
3. Edit the elastic and/or scheduled fields in the panels that appear. These are the same fields described in Create a Scale Group (threshold, operator, watch period, period duration, cooldown for elastic; recurrence and cardinality for scheduled).
4. Select Update to save, or Cancel to discard.

note

The saved image, plan, and encryption setting are fixed for the life of the scale group and cannot be edited. To change them, create a new scale group.

warning

You cannot delete a saved image while a scale group is using it. Delete the scale group first, then delete the image.
